[Swift3] primitive typed parameters in POST body

[TeMob]

Description

Hi
I am struggling with primitive parameters used in the request body of POST requests.
The problem is that primitive parametertypes, such as "string", are forced to be JSON encoded, because all body-parameters are being JSON encoded.
Thats part of the problem. Another problem is that all parameters are being casted to a [String:AnyObject] dictionary, although a plain string will never succeed in doing so.

This is the code that swagger-codegen generated:

open class func myRequestWithRequestBuilder(xyz: String) -> RequestBuilder<ABC> {
	let path = ...
	let URLString = ...
	let parameters = xyz.encodeToJSON() as?  [String:AnyObject]  //<- this will always fail for primitives
	
	let url = NSURLComponents(string: URLString)
	
	let requestBuilder..
	return requestBuilder.init(method: "POST", URLString: (url?.string ?? URLString), parameters: parameters, isBody: true)
}

Swagger-codegen version

2.2.2

Swagger declaration file content or url

post:
   tags:
      - "MyApp"
   description: "description"
   consumes:
      - "text/plain"
   produces:
      - "application/json"
   parameters:
      - in: "body"
         name: "xyz"
         required: true
         schema:
         type: "string"

Command line used for generation

java -jar swagger-codegen-cli.jar generate -i /path/to/my.yaml -l swift3 -o swaggeroutput/

@TeMob can you give an example of the HTTP body? we want to know the request body looks like.

[TeMob]

I can't get it to produce a request, so I can't show you the HTTP-request it sends.

[wing328]

@TeMob I'm not referring to the HTTP request produced by the Swift3 API client.

I want to take a look at the correct HTTP request body to understand what payload is expected by the RESTful backend.

@wing328 I have the same problem. The codegen are trying to parse every body parameter to JSON, even when in swagger editor I put String as input and consumes is text/plain. This is a problem for example when using JWT.

Expected request:

---> HTTP PUT http://localhost/api/users
Content-Type: text/plain; charset=UTF-8
Content-Length: 956

---> END HTTP (956-byte body)
